Consider the following function, which takes a dictionary as its input: def f1(dct) : for x,y in dct. items(): print (y) Next, consider the following function definition, which includes one blank (designated by _.._ A ) to be filled in: def f2(dct) : for x in dct: print (_) Fill in the blank with a Python expression that, if used to replace _.. A in f2, will cause f2 to exhibit the same behavior as f1 for all input dictionaries
